To all whmn it may concern:

Be it known that I, Cnsnum on Lmmosevics, a citizen of the United Statesand resident of New York, county of New York, State of New York, haveinvented certain new and useful Innrovements in Rotary Envelo -Machines,0 which the following is a spec tion.

My invention relates to rotary envelop machines and the object is to imrove the construction of this class of mac ines, increase the capacitproduce a more perfect and uniform'enve op preferably of standardAnother object is to permit any size of envelop to be made without theuse of special or separate machinerv to produce the same as is the casewith other machines.

My invention consists in novel features and combinations for holding andpicking up the envelop blanks off the revolving drum.

It also consists in novel means for turning and guniming the lapels.

It also consists in means for removing the envelo from the cylinder.

It also consists in novel means of removing the made-up envelop from thedrying wheel.

Referring to the drawings, Figure 1 is an end elevation of my improvedenvelop machine; Fig. 2 is a side view of a portion of the same; Fig. 3is a plan view of the same; and Fig. 4 is a section on line A--B, Fig.3; this view also showing a mrtinl front elevation of the lower part 0the machine and also the intermediate and finishing mechanism.

In the drawings 1 and 2 designate the frame of the machine suitably he dapart. The upper part of this frame supports the driviu" shaft 3suitably jonrnulcd thereon. Unto ll is shaft is keyed the drum orcylindcr l by means of a hub 6 connected to the rim or outer body of thecylinder by the c lindcr heads or flanges 5. The head or hinge 5supports the mr pumps, 8, 9, each ha vmg inlet or outlet pipes, 10,which lead from the pumps to the air or suction chamlior 11, two ofwhich are formed oiposite each other in the face of the rim of l n:cylinders. 'lho pistons, 12, of each pump are operated by the groovedcam, 13, fastened to the frame 1 which is the upper part of the mainframe of the machine. The said cam acts upon the pins, 14., fastened onthe pistons 12 to cause reciprocations of the pistons for pumpingpurposes. The arrangement of these pistons is such that when one 15moving outward the other is moving inward, and the object of this willbe hereinafter described.

The air or suction chambers 11, formed in the face of the cylinder arein size equal to a folded envelop. The chambers are each covered with aplate, 15 having erforations as shown and suitabl held own in place. Aninterposed rub er rim, 16, is placed under each plate to insuretightness. The envelop blanks extend over these cham' bers and are heldabove and partly upon the cylinder by means of the resting plate, 19,resting and held on to a separating frame, 20, by means of thethumb-screws, 22. These screws also set and adjust the bla nit-holders,23, which consist of the slotted arms, 23", having upright pins or arms,23" to provide means for the eas manipulation of the blank holders 28. ymeans of the slots be tween the arms 23" and also by means of theupright pins or arms 23", the desired adjustment of the blank holders 23can be secured. The actual points of contact between the blanks and theblank holders are at the bottom of the several pins or arms 23 asclearly shown in Fig. 4.

The separating frames are irovided with an opening somewhat larger t nmthe size of the o )ening in the drum or cylinder, 4, and the s ape ofthis frame is similar to the envelop blank.

It will be seen that the separating frame at each end is connected tothe cross heads, 25, 2o, by rods, 24, which pass through suitablebearings, 27, in tho i'rumc. The resting plate 1'.) is given onintermittent upwurd and downward movement through the medium of thegumwhcul, 28, which is keyed on shaftll. This 'cnr wheel 28 acts uponthe spur whcnl, tllh hcycd on shaft 230, 'ournulcd in the l'runu: l, 2.The cross-bums, 2.3 21", being connected to the cranks, 31, on :lmll 30lay nu-nus ol' the Hula, 3:2, nrc giron tln' ruquired movement when theshaft 30 1S rotated, being lifted and depressed once during eachrotation thereof. The upper part, 1, ofthe frame, 1, 2, also supportsthe shaft 40. This shaft also supports the folder supporting frame, 44,to which are connected the lifters, 41, and turners, 42, 1n such amanner as to permit of their moving up and down upon the cylinder 1.This movement isetfected by the coil-springs, 43, (see lugs. 1 and 3.)Beneath this folder-supporting frame 44 are placed the rollers, 46, usedfor pressing down the turned over lapels. Th s roller is supported onthe frame, 41 which is securely held on the frame of the machine, andpressed down upon the cylinder by the cam, 48, on shaft, 49, supportedon the frame 1, see hig. 1. This shaft 49 is revolved by the gear pinion50, keyed thereon, and into which meshes the intermittent teeth, 51, ofthe intermittent gear wheel, 51, keyed on the main shaft 3. 'l'he shaft49 also supports the gumming roller, 52, the gumn mg surface, 49,thereof being supplied at intervals with the necessary gum by thedistributing roller, 53, on the rocking arm, 54, fulcrunied on frame 1,2, and intermittently operated by the cam 58, on the shaft 55, supportedon the main movement from gear wheel, 56, acted upon by pinion, 50, seeFig. 1.

Beneath the gumming rollers is supported on the frame the angle late orblade 57 used to raise and fold e mmed lapel. And just underneath thishis e is located the roller 54 for p down the gumnied lapel into place.This roller 54 is supported in sliding bearings and is also g ven therequired tension by means of the Spl'1!]gS shown. Further underneath thecylinder is placed the second gumming device being similar in parts andoperation to the one already described. The intermittent revolat-ion ofthe esumming roller 60 of this device is effect by the crank, 64, on agear wheel 65, on the shaft, 66, suitably supported on the frame. Theother end of this crank arm is connected to the gear wheel, 6?, on theshaft, 68, also supported on the frame. The intermitting teet of thewheel, 51, mesh into the gear wheel, 67, and revolve the parts in thesame manner as the parts of the previous mechanism were revolved. Althetime the second grooming is being done and near the linishin of thesome, the folded part of the cove op is expelled from oil the cylinderby the on pump which retained it because at this point the pistonthereof has moved inward and interrupted the suction. lly cxpollin orejecting the made up envelop in the a ovc manner the same is pcrmilh-dto turn and enter the chute, 00', edgeise no it fails. it in then caughtup at the edge by the rollers, GT, 68*,

frame. This shaft 55 derives its.

the latter being mounted on shaft, 69, journaled on frame l.

When the envelop leaves the chute it drops into one of the compartmentsof the dryin wheel, 70, on shaft, 72, suitably sup. porte The shaft, 80,is supported in the frame 1, 2, and is driven by the belt, 81, passingover pulley, 82, see Fig. 1. The shaft 80 at a is rovided with a.cylinder, 80', having a cam aped groove, 86, into which enters the pin,87, of the envelop delivery slide, 88, w 'ch is connected to the devicefor intermittently revolving the dr ing drum. This device consists of aroching arm, 89, suitably supported on shaft, 90, which is given anescapement action against one of the wings of the drying drum. This onlytakes place when the delivery mechanism has shoved oil one envelop. Atthe time this is being done the envelo passes over or before therollers, 92 93 an 94, but before the envelop asses the roller 92 theupper lapel 1S tame and pressed down by the arm, 96, supported on thefinishing bracket, 97, secure on the frame of the machine. This turningarm, 96, is shaped as shown in Fig. 2, the u per or flange portion, 98,is given the a e c and the part (Z is given a curve. Now w on the lapelstrikes the an le 98 it is caused to be lifted and turned an then thecurve completes the same, and the roller 94 finishes the ressi andmanufacture of the envelo otion 15 wan to the rollers, 92,

93 an 94 through t e bevel wheel, 99, on shaft 80, meshing a bevel wheelon the axle, 100, having support in bracket, 97. This axle, 100, on thetop has a large gear wheel which meshes into the inion, 102, on the axleof the roller, 94. T e other end of this roller has another pinion whichmeshes into an idler, 105 transmittin the motion to roller, 93, andthence to ro lot, 92, through the pinion, 106, see Fig. 2.

The operation of the machine herein described 15 as follows: The cnveloblanks which can be of any number are p need nodcr the plate 19 and heldin place by the corner pins or studs 23. The blanks now he upon theperforated plates of the suction chamber F o the pumps 8. The machine isnow set in motion and as the shaft 3 revolvcs the intermittent wheel 28will operate the late 19 and cause it to draw down the blnn ts upon thesuction plate. Instantly this operation takes place, the pump 8 isoperated u )0" by the cam, cousin" the piston thcrco to move outward.'lu-n this takes place the um i will by suction draw down one of the dims closely upon the sunlion plate. Now, as the cylinder 4 revolves in thedirection of the arrow it will carry with it. the blank that has or ishold to it by the suction plate, and hold it thou-non lllllll the lapelturning and gun-lining devices have operated, to be hereinafterdescribed. As the arms turn the blank on the cylinder lifters 41 willcome in contact with the towers, 42, which will lift and turn over theend flaps upon the envelop proper; an

when these flaps are turned SllflltBlBllll? they are res-zed downclosely by the rol er 41'. After the blank has had its end lapel turnedover and pressed down, it is still meld on to the revolving drum by riedthereby to the gumming device, where one of the long lapels is gummed bythe roller 52, intermittently operated upon by the gear \vheel'ol. Inorder to turn over this gummed lapel and press it down upon the turnedover end lapels, the clingingl blank is turned by the drum against the bade 5? which will raise the gummed lap1el as before described and as itturns over t e roller 5% will press it down closely u on the epvelop.The a-rtially finished blan still clings to the rum and is carriedtoward the second gumming device, where the interinittentl gununinroller will gum the loose lape The blan is now ready to be thrown offthe cylinder, which is done at the time the second gurmning is takingplace by the pump 8, and the pistons thereof moving inward through thecam which movement ex is the air and destroys the suction. The c jcct ofexpellin the blank when the unnning 1s takin p ace is to cause the finisied envelop to fa edgewise into the chute 66 and between the travelinrollers, 67 68, when it is carried downwar until it. falls into one ofthe compartments of the drying cylinder 70. After the finished envelohas remained on the drving wheel a suita le length of time, it is throwntherefrom by the ejecting device. That portion which effects the resultis the delivery slide, 88, operated by the cam 86' shoving a aiust theedge of one of the envclops on he drying wheel. At the time an envelophas been shoved outof the wheel, the cscapementdevice is operated forturning the wheel one vane forward. As the delivery slidc' 88 returnsinto place, the rock ing arm 89 is caused to turn so as to act upon oneof the wheel vanes in such a manner as to move it forward. \Vbcn theenvelop is being shoved oil the drying \vhccl it msscs the rollers 92.J3 and the loose lapcl already gunnncd and dricd will come in contactwith the lurniup, lip or plate, Elli, which lifts this lnpcl and causesthe Haunto be turned down. where it is caught up by the rollrr J4 whichcompletely liuishcs the cnvclop for usc. When the cnvclop is beingl'jct'lttl from tho drum by pump 8. the unnp b is holding a blank on tol a! cyliln vrs III the sunnmanner that the pump h caught up the aboveblank. .\t the moment a blank is caught up, an envelop is being expelledfrom the cylinder.
